- Job Shop Gains Control of Volatile Schedule

Every job shop deals with schedule volatility. But when your products are constantly changing and your order mix shifts weekly, even basic scheduling becomes a challenge. How do you schedule production when tomorrow's products might be different from today's?
An assembled products job shop found the answer in Resource Manager for Excel — managing volatile scheduling and inventory needs in just a few hours per month.
Read the full volatile schedule success story.
The Challenge: Constant Change
Jim Muraski, Production Control Manager of the Assembled Products Group, described the core reality: "Our products are constantly changing."
This is the defining characteristic of a high-mix, low-volume job shop. Every week brings different products, different routings, different material requirements, and different delivery commitments. Traditional scheduling approaches — which assume relatively stable production — break down in this environment.
The challenges compound:
- New BOMs needed for each product variation
- Inventory management must adapt to shifting material requirements
- Production schedules become obsolete almost as fast as they are created
- The scheduling tool itself must be fast and flexible enough to keep up with changes
The Solution: Minutes, Not Days
Jim Muraski summarized the value concisely: "For only a few hours per month, the Resource Manager provides the ideal format to configure new Bills-Of-Material, prepare production schedules, and manage our inventory. Since we are already familiar with Excel, there wasn't even a learning curve."
Key Capabilities for Volatile Environments
Rapid BOM configuration — New products can be set up in minutes, not hours. When your products change constantly, the speed of BOM creation determines whether scheduling helps or hinders production.
Integrated inventory management — Material requirements change with every new product configuration. Resource Manager keeps inventory management synchronized with the actual production schedule.
Excel familiarity — Zero learning curve because the team already knows Excel. This means any team member can interact with the scheduling system without specialized training.
Minimal time investment — Only a few hours per month to maintain the scheduling system, even with constantly changing products. This low maintenance overhead is essential for small job shops where everyone wears multiple hats.
Why Volatile Scheduling Requires Specialized Tools
Spreadsheets Cannot Scale Volatility
Many job shops try to manage volatile schedules with raw Excel spreadsheets. This works for simple operations but breaks down when products change frequently. Each new product requires new formulas, new material lookups, and new capacity calculations. The spreadsheet becomes a full-time job to maintain.
Resource Manager for Excel provides the scheduling structure — finite capacity constraints, BOM explosion, inventory netting — while preserving the flexibility and familiarity of Excel. The spreadsheet does the math; you do the thinking.
ERP Is Too Slow for Volatile Shops
Large ERP systems require significant data entry for each new product — creating items, building BOMs, defining routings, updating master data. For a shop whose products change constantly, this overhead is prohibitive. By the time you set up the product in ERP, you might already be done manufacturing it.
Resource Manager's rapid configuration capability is designed for exactly this scenario: fast setup, immediate scheduling, and no wasted data entry on products you may never make again.
Low Maintenance Is Non-Negotiable
For a small job shop, the scheduling system cannot require significant ongoing maintenance. If maintaining the system takes as much time as the manual scheduling it replaced, there is no net benefit. The "few hours per month" maintenance requirement reported by Jim Muraski shows that Resource Manager passes this test decisively.
Lessons for High-Mix Job Shops
Speed of configuration is more important than depth of features. In a volatile environment, the ability to set up a new product in minutes matters more than sophisticated optimization algorithms. Choose scheduling software that matches your speed requirements.
Familiar interfaces reduce adoption risk. The zero learning curve from Excel familiarity meant the entire team could use the system immediately. For small shops, training time is a significant hidden cost.
A few hours per month is the right benchmark. If your scheduling system requires more than a few hours per month of maintenance overhead, it is too heavy for a volatile job shop. Resource Manager for Excel delivers the right balance of capability and simplicity.
Frequently Asked Questions
How does Resource Manager handle volatile production schedules?
Resource Manager provides an ideal format to quickly configure new Bills-of-Material, prepare production schedules, and manage inventory for constantly changing products. The system requires only a few hours per month to maintain even in highly volatile environments.
Can scheduling software work for high product mix manufacturing?
Yes. The assembled products job shop had constantly changing products, yet Resource Manager handled the volatility efficiently. The Excel-based interface meant there was no learning curve, and new product configurations could be set up in minutes.
How much time does Resource Manager require for volatile schedule maintenance?
Jim Muraski, Production Control Manager, reported that for only a few hours per month, Resource Manager provides the ability to configure new BOMs, prepare schedules, and manage inventory. This minimal time investment delivers maximum scheduling control.
